Hardly an episode goes by where there isn't a claim of continuity errors on KUWTK and Sunday night's show was no different.

As Tyga had his say over Rob Kardashian's secret engagement to Blac Chyna he talked about them having a child together - one whole month before they actually announced the happy news they are expecting their first baby together.

Speculation is that either Kylie Jenner's other half is psychic, or the group knew about Blac's pregnancy before the engagement, which isn't how it played out on the show.

As speculation continues to surround the show, he's some of our favourite faux-ments.

Dancer Rosa Acosta claimed Keeping Up With the Kardashians is "not totally real" as she opened up about her brief romance with the sock entrepreneur back in 2011.

Rosa was featured on KUWTK spin-off show, Khloe and Lamar, and during a chat with Radar Online the curvaceous beauty appeared to suggest their relationship was scripted.

"Obviously, as you guys know, reality TV is not totally real," she said.

"So he asked me as a friend to be on the show with him," she continued.

"And recreate a couple of things that may or many not have happened with other people."

Kris Jenner has previously hit out at claims the show is fake and in an interview with The View in February 2013 was forced to deny scenes from a trip to Dubai had been re-shot.

She said at the time: "We had gone to Dubai to film a whole episode and we were there for a week or 10 days. When we came home we had to do our interviews, our testimonials in which we are having to look right at the audience as if we’re talking to the viewer.

"We’re going into a studio and I’m clearly holding my outfit, and Kim is clearly holding hers, and they said ‘oh they’re re-creating scenes’ when in fact we were doing our interviews."
